Work covers module to chassis mounting, aluminum skin, compartment sills, entry doors, patient compartment interiors, cot mount floor structure, roof penetrations, chevron and Star of Life graphics, and paint. Medical equipment, oxygen systems and drivetrain work stay elsewhere. ## Common damage - Paint cracking and seam sealer splitting where the module meets the cab - Lower compartment sill corrosion perforating from the inside out on an aluminum module - Exterior compartment doors that no longer align after the module has shifted on its mounts - Rear entry door frame racked after a swung door caught wind or a post - Grab handle and step mounting pulling out of the entry door frame - Patient compartment cabinet faces cracked at the latch and hinge points - Coved wall and floor junction separating and holding fluid at the seam - Soft or flexing floor structure under the cot mount fastener pattern - Roof AC shroud cracked and antenna penetrations leaking at the base - Chevron sheeting and Star of Life graphics lifting at the edges after washdown ## The cab to module joint: a flex point pretending to be a paint problem Almost every ambulance in service around West Covina is a purpose built module bolted to a chassis someone else made. The cab and the module are two separate structures with different stiffness, and they move relative to each other every time the unit crosses a driveway apron or a gutter pan. The joint between them is engineered to absorb that movement. When people call us about cracked paint or split sealer at the front of the box, they are usually looking at a joint that has stopped absorbing anything. The tell is repetition. Sealer that splits once may be age. Sealer that splits again three months after being redone means the module mounting has loosened or the isolators have crushed, and the joint is now taking load it was never meant to carry. We pull the trim and the boot, inspect the mounting hardware and the module sills, look for elongated holes and for cracks radiating out of the front module corners, and correct the mounting before any finish work happens. Doing it the other way around is a waste of a unit out of service. Sealing and painting a joint that is still moving buys one season at most, and in the meantime water is tracking into the module framing behind the seal. We would rather write a longer estimate that fixes the movement than a short one that puts new paint over an active problem. The estimator will show you what is moving before you commit to anything. - Module mounting hardware, isolators and sill condition checked before any sealer work - Elongated mounting holes and front module corner cracks repaired first - Boot and trim removed so the joint can be seen rather than guessed at - Finish work scheduled only after the joint has stopped moving ## Aluminum module skin and the lower compartment sill Module bodies are aluminum sheet over aluminum framing, and they almost never rot from the outside. Water gets past a compartment seal, past a light penetration or past a failed sealer joint, sits on the compartment floor pan, and works outward at the lower sill where two members meet and where the floor pan turns up. By the time it is visible as blistering paint along the bottom edge of a compartment, the framing behind it has already lost section. Diagnosing that means opening it up rather than sanding it. We probe the sill, remove the affected skin, and look at the framing and floor pan behind it. Where the framing is sound we replace skin and treat the surfaces. Where the framing has gone we cut back to good material, let in new extrusion, rebuild the floor pan turn up, and reseal the whole assembly with a sealant that will survive repeated washdown and the disinfectants used in this service. Two details keep the repair from coming back. First, drainage: compartment floor pans have drains that get blocked by debris and by previous sealer work, and a clear drain is worth more than any coating. Second, isolation at every stainless fastener into aluminum framing, since that couple is what starts a lot of these failures. Both get addressed as part of the sill repair rather than as an upsell. ## Exterior compartment doors, entry door frames and grab handles Compartment door alignment on an ambulance follows the module. If the module has settled on tired mounting or the sill has corroded, the opening racks and the door reports the problem long before anything else does. We measure the openings and correct structure first, then set hinges, strikers and seals to a true opening. Doors set to a racked opening will latch for a while and then stop, and crews stop trusting them, which is worse. Rear entry doors take a different kind of abuse. A door caught by wind or swung into a post racks the door frame itself, and the damage propagates into the module rear corner and the header. Straightening the frame back to square is structural work: we let in new corner and header material where required, re-establish the opening, then rehang the doors and reset the hold open hardware. Door check arms and hold opens are replaced rather than bent back, because a bent check arm is what racks the frame next time. Grab handles and entry steps are structural mounting points, not accessories. A handle that a crew loads with body weight several times a shift will eventually pull its fasteners through skin if it was ever mounted to skin. We back every handle and step with a plate or tie it into framing, seal the penetrations, and refinish. The same approach covers the exterior handrails and the fold down steps on higher module builds. - Compartment openings squared before hinge, striker and seal adjustment - Rear entry door frame, corner and header straightened or let in as structure - Door check arms and hold open hardware replaced rather than bent back - Grab handles, handrails and steps backed with plate or tied into framing - All penetrations resealed against repeated washdown and disinfectant ## Patient compartment surfaces, cabinet faces and cleanability The inside of a module is built to be washed down, and every repair inside it has to respect that. Wall and ceiling panels meet the floor in a coved junction with no open seam at the corner, which is what allows a crew to clean a floor without driving fluid into the structure. When that cove separates, or when a repair leaves a butt joint at a corner, the compartment stops being cleanable and starts holding contamination in a place nobody can reach. So interior work here is done with continuous coved detailing rebuilt the way the module maker did it: welded or bonded coving, radiused corners, and sealants rated for the chemicals used in this service. Wall panels are replaced in full sections rather than patched at eye level, because a patch line across a wall is a dirt trap and it reads as a repair to every crew that rides in the box. Cabinet faces, doors and latches are the other half of the interior job. Faces crack at the latch and hinge fastener points, sliding doors jump their tracks, and net retention hardware pulls out of thin cabinet stock. We rebuild faces, reinforce fastener locations with backing, replace latches with matched hardware, and reset the door and drawer geometry. Loose equipment retention hardware is remounted into structure so the next hard stop does not empty a cabinet into the compartment. - Coved wall to floor junctions rebuilt continuous, with no open corner seam - Wall panels replaced in full sections instead of patched mid wall - Cabinet faces reinforced at latch and hinge fastener locations - Sliding cabinet doors and drawer slides reset to correct geometry - Retention hardware remounted into structure rather than into thin stock ## Cot mount floor structure, roof shrouds and antenna penetrations A Stryker cot mount concentrates a very large load into a small fastener pattern in the module floor, and it does it repeatedly, in shear, every time a loaded cot goes in or out. Floors that flex underfoot at the mount, or that show any movement at the fastener heads, have lost the backing structure below the floor covering. That is not a floor covering repair. It is a structural repair, and it is one of the more important ones we do on this vehicle type. We go in from the floor, expose the substructure under the mount pattern, and rebuild it: new backing plate, new or repaired floor framing tied into the module sills, correct fasteners, then floor covering and coving restored over the top. Where a previous repair simply added a thicker plate over soft substrate, that comes out. The load has to reach framing, not a sandwich of plates over a spongy core. The module roof is the other place where small failures cause big interior damage. AC shrouds crack at the mounting feet from vibration and from sun, and antenna bases loosen and let water down the coax into the ceiling. We replace or repair shrouds, rebuild the mounting structure under them, and reseal every roof penetration properly. Where we have removed a light head or an antenna for body work, the mount, the bezel, the harness route and the seal are all our responsibility to put back correctly. ## Remount preparation, graphics and what belongs to your medical provider Remounting a module onto a new chassis is common in this service, and the body and structure side of it is work we do. Before a module is moved it needs an honest condition assessment: sill corrosion, floor structure at the cot mount, module corner cracking, door and compartment squareness, roof penetrations and skin condition. We do that assessment, carry out the body, structural and interior repairs the module needs to be worth moving, and refinish it. The mechanical transfer and everything electrical or medical inside it stays with the remounter or your ambulance service provider. Graphics are part of putting a unit back into service. Rear chevron sheeting, body side striping, Star of Life graphics, agency identity and unit numbering all come off before paint and go back to measured original placement afterward, on cured and prepared finish. Reflective sheeting laid on green refinish lifts at the edges the first time the unit is washed, so the graphics schedule follows the paint schedule. Where sheeting is faded or damaged we reorder to the same spec rather than reusing something that will not match. The scope boundary is worth stating plainly. We do not service, install or certify medical equipment, oxygen systems, suction, patient monitoring or any clinical device. We do not design or certify emergency lighting or siren systems, though we do handle mounting, penetrations, harness routing and sealing where a body repair required removal. We do not touch engines, drivetrains, transmissions or brakes. All work is performed in shop at Yorba Linda. From West Covina it is about 22 miles, usually 30 to 45 minutes on the 10 or the 60 west to the 57 south, then the 91 east to Imperial Highway.

Why does it come back? Because the joint is still moving. That seam is designed to absorb flex between two separate structures, and when module mounting hardware loosens or the isolators crush, the seam starts carrying load instead. Resealing and repainting it will look right for a season and then split again. We check the mounting, the module sills and the front module corners first, correct what has moved, and only then redo sealer and finish. ### Our floor feels soft where the cot locks in. Can that be reinforced without gutting the box? Usually, yes. We expose the substructure under the cot mount fastener pattern from the floor side, replace the backing plate and any deteriorated floor framing, tie the repair into the module sills, then restore floor covering and coving over it. It does not normally require stripping the whole interior. What it does require is going below the surface, since adding another plate over soft substrate just moves the failure a few inches. ### Can you get a module ready to remount onto a new chassis? The body and structure side, yes. We assess sill corrosion, cot mount floor structure, module corner cracking, compartment and door squareness, roof penetrations and skin condition, then carry out the repairs and refinish so the module is worth moving. The mechanical transfer onto the new chassis, and all electrical and medical work inside it, stays with your remounter or ambulance service provider. Tell us at the estimate which parts of the job you want us to carry. ### Do you work on the oxygen system or the medical equipment while the unit is in? No. We do not service, install or certify medical equipment, oxygen systems, suction or patient monitoring in any form. We also do not design or certify warning light and siren systems. Where a body repair required a light head or antenna to come off, we handle the mount, the penetration, the harness routing and the resealing, because that is body and sealing work. Everything clinical stays with your equipment provider. ### The interior walls in the patient compartment are stained and the coving is peeling away. Can that be redone? Yes, and it is worth doing properly. We replace wall panels in full sections rather than patching mid wall, then rebuild the coved wall to floor junction continuous so there is no open corner seam holding fluid. Sealants are chosen for the disinfectants used in this service. Cabinet faces, latches and drawer slides usually get attention at the same time, since the same units tend to show wear in all of those places together. --- OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887.
